So long and thanks for all the fish

In the January edition of BBC Focus magazine, I take a look at what’s happening with the world’s fisheries. Have we already passed ‘peak fish’, the point where each year, the oceans provide fewer fish for people to eat? And if we have, what can we do about it?

I speak to experts on the latest situation with overfishing and look for signs of hope that the problems can be fixed, using a mix of smart thinking, the latest technologies and persuading consumers to care more about the fish they eat.
